DRIVING MECHANISM.

Specification of Letters Patent Patented June 26, 1906. I

' Application filed August 17, 1905. Serial Ito-274,582.

pertains to make and use the same.

This invention relates to driving mechanisms, and has for its object to provide a mechanism adapted for use in driving a separator, the entire apparatus being exceedingly simple and compact.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a side elevation of the present separator, a portion of the spring-casing being broken away. Fig. 2 is a longitudinal section of Fig. 1. Fig. 3 is a top plan view showing theline 2 2, on which Fig. 2 is taken. Fig. 4 is an enlarged detail view of the speed governor.

Referring now to the drawings, the present invention comprises a casting 5, including a supporting-standard 6, having a head 7 at its upper end, this head being flattened and having a chamber therewithin inclosed by side walls 8 and 9 and a connecting edge wall 10. Within this chamber there is located mechansim, to be presently described, and the head includes a rearward removable portion 11, which may be removed to permit of oiling the mechanism.

J ournaled transversely of the head, at its upper portion thereof, there is a horizontal shaft 12, which extends outwardly beyond the side wall 8 of the head and which carries 7 a gear-wheel 13, this gear-wheel meshing with a pinion 14, carried by a shaft 15, the latter in turn carrying a gear-wheel 16. The shaft 15 is journaled horizontally in the head below the shaft 12, and a shaft 17 is journaled in the head below the shaft 15 and carries a pinion 18, with which the gear-wheel 16 is meshed, the shaft 17 carrying the gear-wheel 5o 19, which meshes with a pinion 20, carried by a shaft 21, which is journaled in the head and which has a gear-wheel 22, meshing with apinion 23, mounted upon a shaft 24. The shaft 24 carries aworm-gear 25, and this worm-gear meshes with a worm 26, carried by a vertical shaft 27, which is journaled in a forwardlyprojecting cylindrical enlargement 28 of the head. The shaft 27 extends upwardly from the enlargement 28 and has a separator 29 connected thereto for operation thereby. A centrifugal speed-governor of the expanding type is mounted upon the shaft 24, as shown at 32.

Revolubly mounted upon the outwardlyextending portion of the shaft 12 there is a circular casing 32, and within this casing.

there is located a coil-spring 33, which surrounds the shaft and which is secured at its inner end thereto, the outer end of the spring being secured to the casing. Upon its periphery the casing carries ratchet-teeth 34,

and pivoted upon the outer surface of the wall 7 of the head there are dogs 35, arranged to lie normally in engagement with the teeth 34 to hold the casing 32 against rotation under the action of the spring. Loosely mounted at one end upon the shaft outwardly of the casing 32 there is an arm 36, having a laterally-extending handle 37 at its outer end,

and this arm carries a pivoted dog 38, which lies in engagement with the ratchet-teeth. It will thus be apparent that the arm may be moved through an arc, the dog 38 engaging the teeth to energize the spring, and the dog slipping over the teeth during the return movement of the arm. It will thus be apparent that the separator proper will be rotated through rotation of the shaft 12 by the spring 33.

What is claimed'is A mechanism of the class described comprising a revoluble shaft, a circular casing revolubly mounted upon the shaft, a coilspring within the casing, said spring being secured at its inner end to the shaft and at its outer end to the casing, said casing having peripheral ratchet-teeth, dogs located adjacent to the casing and lying in engagement with the ratchet-teeth, said teeth and dogs being arranged for cooperation to hold the easing against rotation under the action of the spring, an arm'pivoted upon the powershaft outwardly of the casing, and a dog pivoted to the arm and arranged for engagement 5 of the ratchet-teeth to revolve the casing against the action of the spring to energize the latter.
